Title: Digital circuit checker
Inventor: IKEDA NOBUO
IPC: G01R31/02
Filed: 1991-05-14
Abstract: PURPOSE:To easily compare signal waveforms found in two points to be checked by applying a pulse of the same pulse width as a dead time band set by a reset pulse generating means to an agreement/disagreement judging means. CONSTITUTION:To take the difference between the signal waveform in a point A to be checked and the signal waveform in a point B to be checked having a time difference to the signal waveform in the point A, a comparing means 1 is provided. A reset pulse generating means 3 generates a reset pulse having pulse width and polarity as compensating the propagation delay time between the points A and B by use of the output of the comparing means 1, and applies it to an agreement/disagreement judging means 2. The judging means 2 judges that the signal waveforms in the points A and B are coincident when the time difference from the comparing means 1 is within the pulse width, judges that the waveforms are different to each other when it is outside the pulse width, and transmits the output corresponding to each case. Thus, the comparison of signal waveforms found in two points to be checked can be easily performed with a small-sized device.

IPC: G11B20/10
Filed: 1991-04-15
Abstract: PURPOSE:To obtain a waveform equalizer with small size and high performance by comparing the amplitude level of a regenerative signal and a prescribed reference voltage, adjusting the gain of an amplifying means to a prescribed gain for the regenerative signal below a prescribed level and expanding the waveform. CONSTITUTION:The regenerative signal is inputted to the buffer amplifier 2 and the comparators 4, 5 of a waveform expanding circuit 1. By the comparator 5, a signal allowing operation when the amplitude level of the regenerative signal is larger than the reference voltage V1 is outputted to the comparator 4. By the comparator 4, the amplitude level is compared with the reference voltage V2, a control signal is outputted to a gain controller 3 so as to adjust the gain of the buffer amplifier 2 to the prescribed gain when the regenerative signal is below V2. By this configuration, the waveform equalizer capable of expanding the waveform of a signal component whose amplitude level of the regenerative signal is attenuated and equalizing the waveform with high performance in spite of small size is obtained.

Title: Flow rate control valve
Inventor: KIDOUCHI YASUO
IPC: F16K31/40
Filed: 1989-04-26
Abstract: PURPOSE:To reduce power consumed by constituting with a pressure receiver having a pressure receiving area equal to that of a valve body, a back pressure chamber partitioned, while being narrowly communicated with a primary side, with the pressure receiving body, a communication hole communicating between the back pressure chamber and a valve body secondary side, a pilot valve for opening/closing the communication hole and lifting the valve body, etc. CONSTITUTION:With the energization of a solenoid 6, a plunger 7, resisting a spring 8, is attracted, and a communication hole 19 is opened with a pilot valve 22. Then a back pressure chamber 17 and a downstream secondary cham ber 18 become equal in pressure. Because the pressure receiving areas of a piston 13 and a valve body 14 are made equal, the valve body 14 receives no load with respect to the fluid pressure. When the energization to the solenoid 6 is further increased, the lift of the pilot valve 22 increases. A guide cylinder 23 together with the piston 13 are lifted to flow fluid. Under deenergized condi tion, the pilot valve 22 closes the communication hole 19 and no force is applied to the piston 13, and the valve body 14 is in contact with a valve seat 20 with a primary side pressure. Thus the valve body 14 can be driven with a small driving force.
